摘要
The hysteresis phenomenon has been widely observed in transfer characteristics of silicon nanowire (SiNW) biosensor devices in aqueous environment. Considering the experimental observation in the change of the liquid potential due to the charge flow through the oxide layer, we build up an electrical model for the biosensor system with the solution, SiNW, dielectric oxide, and the back-gated substrate, and investigate the hysteresis behavior based on the model.
